Abstract

The management of Orobanche under the infested field condition is very difficult to achieve because of its micro sized seed, high fecundity and asynchronous germination. Thus an attempt was made to evaluate native AMF isolates against Orobanche emergence in tomato. The experiment was carried out in Orobanche infested soils of Belagavi district during 2018-19. During the investigation different methods of application of mycorrhizal biofertilizer were screened for their ability to suppress of Orobanche i.e. (planting of pre mycorrhized seedling; soil application and the combination of both). The results of the present investigations with respect different methods of applications of mycorrhizal biofertilizer on Orobanche emergence has revealed that planting of pre colonized tomato seedling with mycorrhizal biofertilizer plus soil application of mycorrhizal biofertilizer at the time of planting suppressed the Orobanche emergence (0.00 plot-1), followed by planting of pre colonized seedlin

Orobanche; AM Fungi; Pre colonization; Tomato; Mycorrhizal biofertilizer.

Conclusion

The suppression of Orobanche by AM fungi is chiefly known to be due to depletion of strigolactones by them in the rhizosphere of the host plants. Strigolactones are signaling compound that play a vital role as germination stimulants of the parasitic Orobanche. Hence research of the present investigation is a promising strategy to develop a bio herbicide against parasitic weeds with a special reference to Orobanche in tomato and other solanaceous crops like tobacco, brinjal and others.
